f(x)'s athletic tomboy Amber appeared on KBS 2TV's 'Escape Crisis No. 1' on May 18 and recalled a skateboarding accident from the past.  

She said, "I skateboarded often since I was young," and surprised the MCs on the show this day with her versatile talents. The MCs asked, "Have you ever gotten hurt from riding a skateboard?" Amber responded, "Three of my front teeth are fake. They broke because I fell over while riding my skateboard. I also have a lot of scars on my legs from falling."

Also on the show, Kim Young Cheol said that the method to doing well on variety shows was to react well. He advised, "The reaction is important not only on-air, but also when you're listening to senior comedians talk."

The MCs asked, "Amber, how do you react at times you don't understand Korean?" and she said, "I follow the person next to me and laugh."
